MACHINE FOR SAWING BEVEL SURFACES.

Specification of Letters Patent No; 10,358 dated January 3, 1854.

To all whom it may concern:

Be it known that I, ALFRED C. 0001:, of Russelville, in the county ofLogan and State of Kentucky, have invented a new and useful Machine forCutting or Sawing Bevels of Every Description to Form Miter, Stave, andother Joints, which I denominate the Adjustable Bevel Gaging andIndicating Platform and I do hereby declare that the following is afull, clear, and-exact description of the same, reference being had tothe accompanying drawings, forming part of this specification, in which-Figure 1, is a view of that end of the machine which has the index andpointer arranged on it; in this view the red lines illustrate the bevelposition of the platform, while the black lines designate its horizontalposition. 'Fig. 2, is also a view of the same end of the machine. Theplatform in this view being shown by black lines in an inclined or bevelposition and the pointer moved to one of the numberson the index. I

plate. Fig. 3, is a side elevation of the machinea portion of the framebeing broken away to show the manner in which the platform is suspendedand allowed to turn on its center. Fig. 4, is a plan or top view of thesame, showing the sliding car'- riage, its adjustable rest, anddog orstop. Fig. 5, is a vertical transverse section of the sliding carriagethrough the line a, a, in F ig. 4. This view shows the manner in whichthe guide rails of the said carriage are adjusted to suit the bevel atwhich the platform is set. The red lines showing the manner ofadjustment.

Similar letters of reference in each of the several figures indicatecorresponding parts.

The nature of my invention consists in an adjustable swinging bevelgaging platform or bench which is supported by a strong stationaryframe. The top of said platform serving as a carriage for feeding thestuff in an angular or straight direction up to a saw passing up throughand working in a long slit in the carriage as it is moved back and forthover the adjustable platform. The guide pieces or side rails of thiscarriage being made adjustable to allow the platform to be adjusted tosuit any description of bevel desired to be cut. And the side rest anddog against which the stuff lies or rests being also adjustable so as tocut any desired flare or give the stuff ;right angle to any angledesired.

any angle lengthwise that may be desired. The shaft upon which thisplatform swings being: provided with a needle or index pointer on one ofits square ends which v pointer is moved to a certain number on an indexplate, attached to one end of the stationary frame, as the platform isadjusted to give a certain bevel; the said plate or index scale beingset to suit the kind of work being done and can be marked out so as toindicate any angle or bevel from a To enable others. skilled in the m to'make and use my invention I will proceed to. describe its constructionand operation.

This machme may be used in connection with either a circular or uprightsaw, or

with horizontal planes, worked by a pitman, v slide and flywheel orotherwise. I shall however only describe it as applied to a circularsaw,,as thatis the one shown in the drawing.

A, represents the main frame which sustains the swinging platform.

B, is the-swinging platform, made adjustable and turning on and with thecentral'or main shaft Qwhichextends entirely across the main frame andrests, in recesses cut in the top of the three main'supporting 5 postsA. and D, as seen in Figs. 1, 2, and 3..

This platform is attached by each of its ends, on one side, to swordpieces or arms E, E, by pins a, a, which serve as thefulcra for saidplatform to turn upon at this point. The sword arms having slots 6, cutin them for the -set screws 03, (Z, to work in when it is desired toraise or lower the said 'arms and the platformthese set screws servingwith the arms to retain the platform in a fixed horizontal or inclinedposition and,

'the arms allowing the platform to be susceptible of any desiredadjustment, as will be evident from the drawing Figs. 1 and 2.

F, F, are segmental braces let into the vtwo end or cross pieces f,f,-of the movable platform; these braces each have a segmental shapeslot 9, cut in them, for the set screws 71., h, to work in as theplatform is moved in the path of a vertical circle, as shown in Fig. 1,by red lines'these braces serve to assist the sword arms in keepingsteady the platform after it has been turned to the inclined positionshown in Fig. 2. The set screws being tightened after the platform isset to cut the proper bevel. By turning the platform to the positionshown by red lines in Fig. 1, the board J, shown by blue lines will becut at an angle as is evident from the drawing, for the saw alwaysmaintains its vertical'position.

G is the pointer or needle secured fast on the square end of the mainshaft C, as seen in Figs. 1 and 2; this needle moves with said shaft andpoints to the numerals on the index plate H, as seen inFigs. 1 and 2. Asthe platform is adjusted to givea bevel of the pointer is moved to thenumerals which designate such an angle on the index plate, and soon,just according to the desired bevel being cut. This index plate may, beset so asto give the very slightest as well as the greatest angle andthe-operation of cutting joints for staves of all kinds of cooperage isthus controlled very efi'ectu- Z the board to rest against, this isattached to ithe side rest and is also adjustable by the set 5 screw 1),and slot w, as seen in Fig. 4. This gmachine is very simple and cheapand it effects a great saving in time and labor.

ally, also every description of bevel employed in joinery may be cutwith ease and facility.

I, is the feed carriage. It slides over the ways 7s, 73, the rails Z, Z,guiding and keeping it on the said ways. These rails Z, Z, are 3 ,tosecure by Letters Patent, is-- adjustable by the slide plates m, m, andset screws 71,, n, which plates are set transscribed of an adjustableswinging bevel gagving platform provided with a slidin riage I, whichhasadjustable guide rails Z, Z, 5 and adjustable heel and side rest J, andL; and pointer G, in combination with an in- E dex plate H, and cutter JI the whole being versely in the bottom and near each end of thecarriage and slide freely in their seats; these rails are madeadjustable so as to allow the platform to be set at the greatest angledesired. The necessity of this adjustment will be seen in Fig. 1, for asthe platform is adjusted the face of the saw J, is brought very near theedge of the slot K, in the carriage and that the saw is prevented fromturning freely until these rails and carriage are moved toward it andthe saw consequently made to have arplace directly in the center of theslot. The saw has no lateral movement whatever and only has a .use ofthis rest in connection with the adjjustable platform-the flare andbevel of Estaves maybe cut atthe same time for it willbe evident thatthis rest can be set at any angle desired by the slots and set screws.pivot in its center the same object can be The pivot also serving asaset i SCI'GW'fLS well as a fulcrum.

i effected.

By having this rest to turn on a L, is the heel rest or dog for the endof What I claim as my invention and desire The employment in the mannerherein deconstructed, arranged and operating in the manner and for thepurpose herein descrlbed.
